Erysimum plant named ‘HONEYBERRY’

ABSTRACT

A new and distinct variety of  ERYSIMUM  plant named ‘HONEYBERRY’ which is characterized by compact freely-branching habit, variegated foliage, crimson and mauve sweetly scented flowers which are produced from spring until early summer. In combination these traits set ‘HONEYBERRY’ apart from all other existing varieties of  ERYSIMUM  known to the inventor.

Genus and species: Genus: ERYSIMUM. Species: ×hybrida.

Denomination: Denomination: ‘HONEYBERRY’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofErysimum, also commonly known as perennial wallflower, which is grown asan ornamental for use in planted containers and in the garden andlandscape. The new cultivar is known botanically as Erysimum×hybrida,and will be referred to hereinafter by the cultivar name ‘HONEYBERRY’.

‘HONEYBERRY’ arose and was discovered by the inventor in 2009 as anaturally occurring variegated branch sport on a single plant in a cropof Erysimum plants which had been raised from seed at the inventor'snursery in Walberton, West Sussex, United Kingdom. The seeds wereunnamed and all plants raised from the seed were non-variegated, exceptfor the single plant with the observed variegated branch sport.

‘HONEYBERRY’ was first asexually propagated by the inventor in 2010 inWalberton, West Sussex, England. Asexual propagation was accomplishedusing softwood cuttings. Since that time, under careful observation, thedistinguishing characteristics of ‘HONEYBERRY’ have been determinedstable and uniform, and to reproduce true to type in successivegenerations of asexual propagation.

SUMMARY OF THE INVENTION

The distinguishing characteristics of ‘HONEYBERRY’ are as follows: Incombination these traits set ‘HONEYBERRY’ apart from all other existingvarieties of Erysimum known to the inventor. ‘HONEYBERRY’ has not beentested under all possible conditions and phenotypic differences may beobserved with variations in environmental, climatic, and culturalconditions.

-   -   1. ‘HONEYBERRY’ is hardy and perennial in USDA Zone 7 and        warmer.    -   2. The growth habit of ‘HONEYBERRY’ is compact and        freely-branching.    -   3. The foliage of ‘HONEYBERRY’ is variegated, consisting of        bright yellow colored margins on gray-green leaves.    -   4. The buds and opening flowers of ‘HONEYBERRY’ are crimson in        color.    -   5. The fully open flowers of ‘HONEYBERRY’ are light mauve in        color.    -   6. ‘HONEYBERRY’ blooms from spring until early summer.    -   7. ‘HONEYBERRY’ achieves a height of 30 cm and a spread of 20 cm        in the first year of growth.    -   8. ‘HONEYBERRY’ achieves a height of 30 cm-40 cm and a spread of        30 cm-40 cm when mature and established as a perennial.    -   9. ‘HONEYBERRY’ grows well in full sun to part shade, in fertile        well-drained soil.

COMPARISON WITH KNOWN VARIETY

The only other cultivar of variegated Erysimum known to the inventor isthe variety ‘WALFRASTAR’ (U.S. Plant Pat. No. 23,101). ‘HONEYBERRY’ and‘WALFRASTAR’ may be distinguished by flower color. Whereas the flowersof ‘WALFRASTAR’ are yellow in color, the flowers of ‘HONEYBERRY’ arecrimson in color when opening, becoming light mauve when fully expanded.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color drawings illustrate the overall appearance of‘HONEYBERRY’ showing the colors of its foliage and flowers as true as itis reasonably possible to obtain in colored reproductions of this type.Both drawings have been made from a one year old plant.

FIG. 1 depicts a whole plant of ‘HONEYBERRY’ at time of first flowering,in the spring. The illustrated plant has been grown in a 1 litercontainer in a frost-free greenhouse at the inventor's nursery inWalberton, West Sussex, England.

FIG. 2 depicts a close-up view of the inflorescence of ‘HONEYBERRY’ anddepicts the crimson buds and the flowers which are crimson when opening,becoming light mauve when fully open.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of ‘HONEYBERRY’ as grown in aone liter container in a frost-free greenhouse in West Sussex, UnitedKingdom. The color determinations are in accordance with the 2007edition of the Colour Chart of The Royal Horticultural Society, London,England, except where general color terms of ordinary dictionarysignificance are used. Growing conditions are similar to those of otherErysimum.
